In a shallow bowl, mix the flour, garlic powder, salt, and black pepper.
Dredge each piece of chicken in the flour mixture, coating all sides evenly.
Heat a large skillet over medium heat and drizzle with oil.
Place the chicken in the pan, cover, and cook for 3-5 minutes.
Flip and cook for another 3-4 minutes, until golden brown and fully cooked through.
Transfer the chicken to a plate and set aside.
